appairage et socket bluetooth

**m.borghesi** · 08/12/2010, 14h30

Salut à tous,

Voici mon problème :

J'ai développé une application sur un téléphone (le HTC désire) et j'ai essayé de la passer sous une tablette (samsung galaxy tab).
Chose importante à savoir : le téléphone est sous 2.1 et la tablette sous 2.2.

Mon application utilise un périphérique bluetooth afin d'échanger des données avec l'application.
J'obtiens des différences assez bizarre...

Premièrement, sur la tablette je dois, à chaque nouvelle connexion, renseigner le code d'appairage du périphérique bluetooth (chose que je ne dois pas faire sur le téléphone...).
Normal ?

Deuxièmement, lorsque je quitte l'application depuis la tablette celle ci plante totalement... Alors que sur le téléphone il n'y a aucun probleme.
J'ai repéré le problème cela viens de la socket bluetooth apparement, puisque quand je vire le code associé ça plante plus... (mais mon application devient du coup inutile^^).
Je précise que je ferme proprement la socket après chaque utilisation...

Voici comment j'utilise la socket pour la connexion :

public BluetoothSocket connectTest(String adr)
{
	BluetoothDevice hxm;
	Method m;
 
	try 
	{	
		hxm = BluetoothAdapter.getDefaultAdapter().getRemoteDevice(adr);
		m = hxm.getClass().getMethod("createRfcommSocket", new Class[]{int.class});
		socket = (BluetoothSocket)m.invoke(hxm, Integer.valueOf(1));
 
 
	}
	catch (SecurityException e) 
	{
		// TODO Auto-generated catch block
		e.printStackTrace();
	} 
	catch (NoSuchMethodException e) 
	{
		// TODO Auto-generated catch block
		e.printStackTrace();
	} 
	catch (IllegalAccessException e) 
	{
		// TODO Auto-generated catch block
		e.printStackTrace();
	} 
	catch (InvocationTargetException e) 
	{
		// TODO Auto-generated catch block
		e.printStackTrace();
	}
 
	return socket;
 
} // connectTest

J'ai essayé aussi avec une autre méthode (qui marche sur le téléphone mais qui plante la tablette) :

public BluetoothSocket connectByAndroid(BluetoothDevice mmDevice)
{
	BluetoothSocket mmSocket=null;
	UUID myUUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");
 
	try 
	{
		// MY_UUID is the app's UUID string, also used by the server code
		mmSocket = mmDevice.createRfcommSocketToServiceRecord(myUUID);
		//mmSocket.
	} 
	catch (IOException e) 
	{
		io.errorMessage("btcontroler creatRfcom l:154 :"+e.getMessage());
	}
 
	return mmSocket;
 
} // connectByAndroid

Une idée du problème?

Ce que je comprend absolument pas c'est que toutes ces méthodes marche mais lorsque je quitte le programme ça plante...

Salut,

Quand tu dis que ça plante ou ça bug, as-tu une exception qui est levée ?
Si oui pourrais-tu nous la poster ici ?

Merci.

c'est justement ce que je ne comprend pas...
Lorsque je regarde le DDMS il n'y a rien d'anormale, aucune erreure.

Voici le log DDMS à partir du moment ou je quitte l'application :
